Ozone affects pollen allergens: at ozone levels typical of photochemical smog, more allergens are formed in pollen. This connection has been demonstrated in the rye plant and is now being published in the prestigious Journal of Allergy Clinical Immunology. The project funded by the Austrian Science Fund FWF shows that elevated ozone levels during maturation increase the protein and allergen contents of rye pollen. This points to a relationship between current environmental problems due to
